... and of those .. how many actually like it (the Blaze part). In any case, it is hard to name a band with decades of longevity that does not have at least one period that is pretty much ignored by both the band and the large chunk of the fans. "new singer that came in for 2 albums that did not have much success" is generally a good candidate for such a period. At least Maiden played some Blaze stuff when Bruce came back and put some of it on live albums/the best of ... not 100% ignored, but not celebrated nearly as much as post/pre Bruce leaving
Well, I certainly know the ones who can't stand Blaze material, but they're also sceptics about reunion era Maiden. Others are vaguely aware there was a different singer for a while, and that's about it.
